The Altman UV-703 is a compact, high output blacklight fresnel. It is designed to provide high intensity illumination of fuorescent materials at distances up to 150 feet. The fxture does not require any fans for cooling, resulting in extremely quiet operation. The fxture is equipped with barndoor rollers and an integral wire mesh safety screen in front of the lens. The ballast is simple to operate with a single on/of switch. A special fresnel lens flters out harmful UV-B and UV-C wavelengths and almost all visible light.
